Photos: Atlas 5 rocket soars from West Coast

Here’s a look by the numbers of the previous Delta 4 flight history and the remaining flights of the rocket named Delta.

Making its first flight, a privately-funded air-launched rocket developed and built by Richard Branson’s Virgin Orbit failed to reach space Monday after release from the company’s modified 747 carrier airplane over the Pacific Ocean.

Officials hailed an action-packed three-minute test flight Tuesday over Cape Canaveral that exercised the Orion spacecraft’s launch abort rocket, a key safety system on the capsule NASA is developing to carry astronauts back to the moon.
